<br /> <br /> <br /> <br />6 <br /> <br /> <br /> ( <br /> ) <br /> <br /> <br /> <br />Figure 5: Plot of wind speed vs. duration <br />4. The intersection of the red curve and blue curve <br />identifies the “Design Overland Wind Speed ( )” <br />of 52 mph or 76 ft/sec. Find the overwater wind <br />speed using Figure 3 and Equation 3. This gives a <br />wind ratio of 1.21 from the figure and an adjusted <br />overwater wind speed ( ) of 63 mph. <br /> <br />5. Find the wind setup using Equation 4. <br /> <br /> <br />6. Find the wave height using Equation 5. <br /> <br /> ( <br /> ) <br />7. Find the wave length using Equation 6. <br /> ( <br /> ( <br /> ) ) <br /> <br /> <br />8. Find the wave runup height using Equation 7. <br /> <br /> ( <br /> ) ( ) <br /> <br />Results: <br />The estimated maximum significant wave height is 3.2 <br />feet with an overwater wind speed of 63 mph. The <br />corresponding maximum height the water will reach <br />from the still water flood level is 3.5 feet, which is the <br />sum of wind setup (0.6 foot) and runup (2.9 feet). <br />
